Hello!
4 of course. It has a more heroic point of view, clear action, no bullshit background. You just need to add those bugs wings.
The 3rd one has a good classic painting vibe, with a simple yet efficient composition.
2 is nice too but i bet she is the kind of person who drinks from the bottle. Also, does she brings her glass when hunting in a swamp?
I'm impatient to see your next move.
